Developed foundational hardware design assets for the rover system in the robotique-udes/PCB repository, focusing on the Rover Ethernet Switch and Rover Servo Controller. Leveraged CAD and PCB design skills to create detailed STEP models, enabling early-stage mechanical integration and assembly planning for future production. Emphasized robust version control practices by improving design file management and commit traceability, supporting efficient collaboration and repository hygiene. The work established a technical baseline for hardware integration, accelerating prototyping efforts. No major bugs were addressed during this period, with the primary contribution centered on delivering reusable hardware design files and metadata for downstream engineering teams.
